I've been using helios tubes on my last few commercial shoots, and I have to say, they're quickly becoming my favorite part of the kit. If you've ever spent hours wrestling with heavy C-stands or trying to hide thick power cables just to get a decent hair light in a tight corner, you probably already know the struggle. That's exactly where these little lights come in to save the day. They're basically the shorter, more agile younger sibling of the famous Titan tubes, and honestly, for a lot of what I do, they're actually more useful.
When you're working in a cramped space—like the interior of a car or a tiny home office—a four-foot tube is often just too much to handle. You end up hitting the ceiling or having to flag off half the light anyway. The helios tubes sit right at about two feet long, which I've found is the "Goldilocks" size for about 80% of my close-up work. They're small enough to hide behind a computer monitor or tuck under a kitchen cabinet, but they still pack enough punch to actually make an impact on the exposure.
One thing that really surprised me when I first started playing with them was the sheer color quality. I've used plenty of cheap LED sticks in the past that made skin tones look a bit well, sickly. But these things have a TLCI and CRI that are off the charts. Whether you're trying to match perfect daylight or you're going for some weird, saturated neon vibe for a music video, the colors stay true. You don't get those weird green or magenta shifts that haunt your post-production nightmares.
Why the Size Matters More Than You Think
It's easy to think that bigger is always better with lighting, but anyone who's ever tried to rig a large fixture in a bathroom for a "getting ready" scene knows that's a lie. The portability of helios tubes is their secret weapon. Because they're half the size of the standard Titans, you can fit an entire kit of eight tubes into a case that's actually manageable. I can toss the case in the back of my hatchback without having to fold the seats down, which is a small win, but those small wins add up on a long production day.
I recently did a shoot where we needed to light a person sitting in a parked car at night. Usually, that involves taping tiny LED pads to the dashboard or trying to shove a light panel into the footwell. Instead, we just used two helios tubes. We tucked one in the back seat for a subtle rim light and handheld another one just out of frame to create some moving "streetlamp" effects. Since they're battery-powered and controlled via an app, we didn't have a single wire running out of the car. It made the whole process about ten times faster.
Wrestling with the Control App
Now, I'll be honest with you—the Astera app (which is what you use to run these) has a bit of a learning curve. It's not exactly "plug and play" the first time you open it. It feels a bit like looking at a flight deck if you aren't used to it. But once you spend an hour or two clicking around and figuring out how to group the tubes, it's incredibly powerful.
The best part is the "Talkback" feature. You can check the battery status of every tube right from your phone or tablet. There's nothing worse than rigging a light ten feet up on a beam only to have it die twenty minutes later. With helios tubes, you can see exactly how many hours of juice you have left based on your current brightness settings. If you're running low, you can just dim them down a touch from the ground, and the app recalculates the remaining runtime instantly. It takes a lot of the guesswork and anxiety out of using battery-powered gear.
Built Like a Tank
I'm generally pretty careful with my gear, but film sets are chaotic places. Things get knocked over, bags get dropped, and sometimes it rains when the weather app promised clear skies. One of the reasons I feel comfortable recommending helios tubes is that they're actually built to take a beating. They have an IP65 rating, which basically means they're dust-tight and can handle being splashed with water.
I wouldn't go diving with them, but if you're shooting a scene in the rain or near a pool, you don't have to freak out the second a drop hits the casing. The housing is a tough polycarbonate that doesn't feel brittle. I've seen these things survive some pretty impressive tumbles, and while I wouldn't suggest testing that theory on purpose, it's nice to know they aren't made of glass.
Getting Creative with Effects
Beyond just being a solid white light source, the pixel control on helios tubes is where things get really fun. Each tube has eight individual pixels that you can control independently. This means you can create "flow" effects where color moves from one end of the tube to the other.
If you're doing a product shot—say, a sleek wine bottle or a new smartphone—having a light that can subtly "crawl" across the surface of the glass creates a much more premium look than just a static glow. I've also used them to mimic the flickering light of a television or the blue and red flashes of a police car. Because you can program the frequency and the exact shades of color, it looks much more realistic than the "emergency" presets you find on cheaper lights.
The Mounting Game
Let's talk about the mounting for a second, because that's usually where cheap lights fail. The helios tubes come with these clever little spigots and eye bolts. You can screw a spigot into the back of the tube and pop it straight into a grip head, or use the eye bolts to hang them from the ceiling with some fishing line.
They also have these neat "crossplates" that let you mount four tubes side-by-side to create a larger light source. It's like a DIY softbox but way cooler because you can still control each tube individually. I've used that setup as a key light for interviews when I wanted something that felt a bit more modern and "techy" than a standard circular softbox.
Are They Worth the Investment?
I get asked a lot if these are worth the price tag, especially since there are so many "tube lights" on the market now for a fraction of the cost. My take is that it depends on how often you're on a professional set. If you're just doing a YouTube video in your bedroom once a month, you might not need the heavy-duty build and the wireless DMX capabilities.
But if you're working with clients, you need reliability. You need to know that when you set a color temperature to 4300K, it's actually 4300K. You need to know the battery isn't going to swell and die after three months. For me, helios tubes are one of those "buy once, cry once" pieces of gear. They're an industry standard for a reason.
When I show up to a set and the Gaffer pulls out a case of these, I know we're going to have a smooth day. They just work. No flickering on camera, no weird pairing issues, and no cables for the producer to trip over. In the end, they save so much time during setup and teardown that they practically pay for themselves in saved man-hours. Plus, they just look cool. And let's be real, sometimes looking like you know what you're doing with high-end gear is half the battle in this industry.
